While the Viking hordes might be best known for their destructive and pillaging, thanks to English propaganda as well as Assassin’s Creed Valhalla’s own marketing, they also committed to a lot of settling and infrastructure as well. Although you don’t play as a jarl, Eivor is put in charge of an English settlement early on in Valhalla, and the player is tasked with nurturing the budding township and deciding what buildings to erect.

Assassin's Creed Valhalla is by no means the first game to introduce some base-building elements to break up all the action and violence, but nevertheless, it can be a bit dauntless to decide what to build when the game doesn’t tell you much about the benefits of doing it. To help you with your hooded hardhat, this guide will explain everything you need to know about the settlement building in Assassin’s Creed Valhalla.
